I like the ease of use that ruby on rails provides. But before I
switch over completely from ASP.NET, I would like to know what sort of
gui’s are available for rubyonrails.

I like the asp.net webparts. With webparts, I can divide the website
into zones and then put modules into those zones. The user can then
edit those modules and move them around. It makes everything very
easy for the user and for myself when programming.

Is there any way to do something similar with rubyonrails? Are there
any gui’s out there for sale or free that I can experiment with?

Rails is a young framework and is not targeted at the gui audience.
There are many good IDE’s like Netbeans, but not gui tools like
Dreamweaver. If you must deal with people who can only work with the
gui type interfaces, my suggestion is that you stay with ASP. You
might be able to build a web interface to standard modules that you
create using Prototype & Scriptaculous, but basically this means you
are building the gui tool yourself.
Good luck!

Not quite true

Ruby In Steel Developer is unique in providing a full drag-and-drop
design environment for Rails (‘The Visual Rails Workbench’). It can also
import/export page designs to other editors such as Dreamweaver and
handle the translation between full HTML pages and multiple ERb
templates. We have lots of information, tutorials and screencasts
showing its capabilities - for an overview, take a look here:
